Airworthiness Directives; Turbomeca S.A. Turboshaft Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are superseding airworthiness directive (AD) 2014-01-01 for 
all Turbomeca S.A. Arrius 2F turboshaft engines. AD 2014-01-01 required 
a one-time inspection of the ejector assembly nozzle of certain serial 
number (S/N) lubricating devices and, if a discrepancy was found, 
removal and replacement of the affected ejector assembly nozzle with a 
part eligible for installation. This AD requires the same action as AD 
2014-01-01 and expands the list of affected S/N lubricating devices. 
This AD was prompted by the determination that additional lubricating 
devices, identifiable by S/N, may have an incorrect bonding of the 
nozzle on the ejector assembly. We are issuing this AD to prevent 
failure of the ejector assembly nozzle, which could lead to an in-
flight shutdown (IFSD) of the engine, damage to the engine, and damage 
to the helicopter.

DATES: This AD is effective June 12, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 12, 
2015.

Discussion

    On January 2, 2014, we issued AD 2014-01-01, Amendment 39-17724 (79 
FR 3481, January 22, 2014), (``AD 2014-01-01''), for all Turbomeca S.A. 
Arrius 2F turboshaft engines. AD 2014-01-01 required a one-time 
inspection of the ejector assembly nozzle of certain S/N lubricating 
devices and, if a discrepancy was found, removal and replacement of the 
affected ejector assembly nozzle with a part eligible for installation. 
AD 2014-01-01 resulted from an IFSD of an Arriel 1 engine. We issued AD 
2014-01-01 to prevent failure of the ejector assembly nozzle, which 
could lead to an IFSD of the engine, damage to the engine, and damage 
to the helicopter.

Actions Since AD 2014-01-01 Was Issued

    Since we issued AD 2014-01-01 it has been determined that 
additional lubricating devices, identifiable by S/N, may have the same 
unsafe condition, an incorrect bonding of the nozzle on the ejector 
assembly. Also since we issued AD 2014-01-01, the European Aviation 
Safety Agency (EASA) has issued AD 2015-0057, dated April 1, 2015, 
which requires inspection, and replacement as necessary, of the 
affected lubricating devices.

Related Service Information Under 1 CFR Part 51

    We reviewed Turbomeca S.A. Mandatory Service Bulletin (MSB) No. 319 
79 4835, Version B, dated February 12, 2015. The MSB describes 
procedures for inspecting the ejector assembly nozzle and, if 
necessary, replacing the ejector assembly nozzle. This service 
information is reasonably available because the interested parties have 
access to it through their normal course of business or by the means 
identified in the ADDRESSES section of this AD.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

AD Requirements

    This AD requires a one-time inspection of the ejector assembly 
nozzle of certain S/N lubricating devices and, for any ejector assembly 
nozzle that fails inspection, removal and replacement with a part 
eligible for installation.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because of 
the short compliance time requirement. Therefore, we find that notice 
and opportunity for prior public comment are impracticable and that 
good cause exists for making this amendment effective in less than 30 
days.

Costs of Compliance

    We estimate that this AD affects 96 engines installed on 
helicopters of U.S. registry. We also estimate that it will take about 
1 hour per engine to comply with this AD. The average labor rate is $85 
per hour. Required parts cost about $563 per engine. Based on these 
figures, we estimate the cost of this AD on U.S. operators to be 
$62,208.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, Section 106, describes the 
authority of the FAA Administrator. Subtitle VII, Aviation Programs, 
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in 
Subtitle VII, Part A, Subpart III, Section 44701, ``General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    This AD will not have federalism implications under Executive Order 
13132. This AD will not have a substantial direct effect on the States, 
on the relationship between the national government and the States, or 
on the distribution of power and responsibilities among the various 
levels of government.
    For the reasons discussed above, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends part 39 of the Federal Aviation 
Regulations (14 CFR part 39) as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing airworthiness directive (AD) 
2014-01-01, Amendment 39-17724 (79 FR 3481, January 22, 2014), and 
adding the following new AD:

2015-10-07 Turbomeca S.A.: Amendment 39-18163; Docket No. FAA-2013-
1003; Directorate Identifier 2013-NE-33-AD.

[[Page 30349]]

(a) Effective Date

    This AD is effective June 12, 2015.

(b) Affected ADs

    This AD supersedes AD 2014-01-01, Amendment 39-17724 (79 FR 
3481, January 22, 2014).

(c) Applicability

    This AD applies to all Turbomeca S.A. Arrius 2F turboshaft 
engines.

(d) Unsafe Condition

    This AD was prompted by the determination that additional 
lubricating devices, identifiable by serial number (S/N), may have 
an incorrect bonding of the nozzle on the ejector assembly. We are 
issuing this AD to prevent failure of the ejector assembly nozzle, 
which could lead to an in-flight shutdown of the engine, damage to 
the engine, and damage to the helicopter.

(e) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.
    (1) For engines equipped with a lubricating device having an S/N 
listed in Figure 1 to paragraph (e) of this AD, within 30 days after 
the effective date of this AD, inspect the ejector assembly nozzle 
and the tightening torque. Use paragraphs 4.4.2.1 through 
4.4.2.3.4.2 of Turbomeca Mandatory Service Bulletin (MSB) No. 319 79 
4835, Version B, dated February 12, 2015, to do the inspection.
    (2) For any part that fails the inspection required by paragraph 
(e)(1) of this AD, before further flight, remove and replace the 
failed part with a part eligible for installation.
